In our case, unlike the other who has Swanubhuti as the only purpose, there is danger of our preoccupation with chores connected with our duties in the outside distracting and taking us away from what we should be doing for Swanubhuti. This is a big risk.
How far we are successful in performing the duties of the Guru without jeopardising the work for Atmalakshaya, in ensuring that the two works are not mutually detrimental but work in such a manner that the sadhana for Atmalakshaya imparts nourishing and vitalising power to our work for loka-kshema and the work for loka-kshema itself is performed in such a manner that the mind gets increasingly pure (chitta suddhi) and enhances the power or intensity of the sadhana itself, - how far we are thus able to neatly balance both the works and act within limits – that will also determine the power of our Asirvadam.
Even then, the real source of power is Narayana only. We should never forget that.
If nothing moves without Him, it means that an Asirvadam also can bear fruit only if His Grace is there. So, we can neither "push away" the namaskara (to Narayana) thinking that we have nothing to do with it, nor think that we have "power" to give Asirvadam and bless.
Then, what should we do? When you lower your body on the floor and prostrate before us, we should say "Narayana, Narayana" with the mouth, remember Narayana, mentally do namaskara to Him, and pray to Him, "Let your Grace do good to these children".
